I i D To all whom u? may concern.-

Beit known that 1-, THOMAS S. HOLT, a citi-' of zen of the UnitedStetes, and e resident Federalshurg, in the county of Caroline and Stateof Maryland, have invented a. new and;

Improved Acetylene-Gas Gen erator, of which the following isa, full,clear, and exact de- The lower end ofthe chamber. '18; is open toscription. v

: The invention relates to an ecetylenegas generator of that class inwhich a quantity of calcium cerbid is discharged into e mass of water,generating the gas-which is subsequently conducted to the gas-holder,the ges holder being connected with devices by which the cerhid-supplyis 'autoinsticeily regulated according to the amount of water in theholder.

The invention resides in certain novel fee- I turesinvolved in the(forbid-feed valve and in the mechanism for automatically operatingthlsvalv'e according to the pressure in the gas-holder;

The invention also relates to other features of major or'ininorimportance involving the construction and arrangement of various partsof the generator.

' ating-chamber to the upper part of said chamshown, said arm bein .orhinged portion to form a closure for the ber. The upper end of the rod34 is connect-r .ed to a lever 36, extending horizontally to a pointunderthe conduit 21, and this lever is joined by a link 37,to. an arm38.- The arm 38 .extends freely through a slot in the shelf 28'and' ishinged to the valvecase 25, as widened at its upper discharge-opening ofthe valve-case and being pivotallyconnected with the valve-stem 27, asshown.

The water in the tank 10 enters the generating chamber through thedivision to the level of the mainbody of water, and said water alsoenters the chamber 29; but the level of the water in the chamber isdependent upon the pressure of gas in the same, the level. dropping asthe pressure rises. This dropping of the water in said chamber will befollowed by a dropping of the float 31, and through the variousconnections 32, 33, 34, 35, 36, 37,'and 38 when the float dro s thevalve 26 will be closed, as indicated in ig.. 1. .As the gas iswithdrawn from said-chamber and the pressure. thereby diminished the we-.duit to one port of a three-way valve 40.

ter rises in the gasholder, lifting the float31, and: by a reverseaction of the said connections 32,33,3 1, 35, 36, 37, and 38 the carbid-.valve is opened, delivering a-further supply of carbid into thegenerating-chamber and producing further generation of gas;

The gas generated in the chamber 18 rises in the conduit 21 and isconducted therefrom by means of a'pipe 39, passing from the con- Fromanotherport of said valve aipipe 41 ex- .tends to the gas-holder orfloat-chamber 29.

" 42 indicates a pipe passing from the pipe 41 to thedelivery-regulator, to be described hereinafter. 7

From the third port of the cook a pipe 47 passes to a vent-pipe 46,leading from t lower part of the chamber 29; The cock 40 is operated bya'h'andle 44,-attach'ed to the stem of the cock and connected alsoto therod 11 and to arod 45. The rod is adapted to en age the-closure 23 ofthe 'chamber 22,

and the arrangement is such that when the cock is in the adjustmentshown in Fig. 5'the rods 11 and45 lock the parts 17 and 23, and whenthe" cock is thrown to the osition shownin Fig. 6 the rods 11 and 45 wil disens gage said parts 17 and 23 and permit the gate 17 to be openedand the closure 23 to be removed. By these devices upon the properadjustment of the valve 40 he gas from the seaeoo generating-chamber maybe conducted directly to the regulator-chamber 29 and at the same timewithdrawn by the pipe 42 to thedelivery devices and service-line, alsoby further adjustmentof the valve 40 the connection with the regulatorchamber and serviceline may be cutoff and the generating-chem;

ber connected with'tlle vent 46, so as-to ventor blow off any gas thatmay be contaim-d in the generator preparatory to opening the chamber forcleaning or repairing. The

parts 17 and 23 cannot be opened until this latter adjustment is made.

As shown bestiin Fig. 2, the pipe 42 carries the gas to a bell 55, thelower end of which is of the chamber and holder 29. On the discharge ehdof'the pipe 42 is a fitting 58, con-- taining a valve 59, which ispivoted to a weighted lever 60, fulcrumcd on the fitting. Said leveris'arranged to he engaged 'by the bell as the same dro s, therebyopening the valve 59. As the hell rises the valve is closed by theweighted lever. In this manner the ischarge of gas from pipe 42'isregulated. The gas is withdrawn from'the top of the bell by a pipe 61,which passes down under the bell and out through the tank 10 intoascrubber 66. (See Fig. 3.) 67 indicates the servicc-pipe passing fromthe scrubber-chamber. This chamber contains coke 63 or other substancefor filtering or scrubbing the gas. In the upper part of the charm ber62 is arranged a l ag 64, of felt or like fabric, distended M a gauzeframe, which bag serves further to clean the gas passing through it. Thebag is attachedto a top section 65 in the chamber 62, and this sectionhas the service'- line 67-leading from it and a cover 66, as shown.

From the foregoing description it is thought that the use andoperationof my invention will be understood. It will be observed that the parts17 and 23 cannot be opened until the valve 40 is thrown into ventingposition,

and its. discharge thereinto is automatically v regulated as explained.It then passes through t e 'urifier or scrubber into the service-line,as s own in Fi 3.

Various changes in the form, proportions, and minor details ofmyinvention maybe resorted to at will without departing fromthe spirit andscope thereof. Hence I conslder myself entitled to all such variationsas uni-y lie within the terms of my claims.
